VERTICAL ROD DRIVE MECHANISM
Patent
·
OSTI ID:4065132
A device is described for supplying air between the upper end of a cylinder and a piston therein attached to a vertical safety rod for a nuclear reactor. The fall of the safety rod into the reactor is cushioned by air trapped between the piston and the lower end of the cylinder. At the upper end of the cylinder air under pressure is supplied against the piston to separate the piston from an electromagnet at the top of the cylinder and thus to speed the fall of the safety rod. When the safety rod is lifted out of the reactor, banging of the piston against ths upper end of the cylinder is prevented by air trapped above the piston.
